"Does he love me" is the question people bring to the cards most often, and also the easiest one to ask badly. Three cards answer it honestly: what he feels, how serious it is, and what answer follows from those two.
It suits the case where feelings haven't been spoken, or have been spoken and the behaviour contradicts them. It doesn't suit the case where you already know and hope the cards will overrule you. And it doesn't answer "will we be together": in tarot, love and a shared future are different spreads.
